Some very expensive rod blanks are made in China and Korea. Like most everything else, it is getting harder and harder to find a US made product. Look at hooks and fishing line. So, being made in China doen't mean it will be a bad blank. It would be nice to get one with a warranty though!

Just an aside... actually, batson's Forecast fly blanks have developed into the RX6 line. the original Forecast were more of a teal color. the RX6s are dark blue and the ferrule fit is better than the older forecast lineup.

I have built several of their Batsons Forecast blanks. I like them pretty well. For what they cost it is a decent quality blank. They do make some higher end fast action stuff but it is similar priced to other manufacturers out there so I haven't bothered to buy them. I mean why test out a Batson priced the same as a Sage? I'll just buy the Sage.
I have built 6'6 2wt, 7'6 3wt, and a few 4wts. Med action at best for sure and very noodly but when fishing small creeks with a 2wt I don't really care. A blast to catch small trout on. Going to try it out on pan fish soon as well.
Oh yeah and my 2wt is a 4pc! Soo much fun!

The rainshadows (RX7&RX8) are both faster then the RX6-forecast blank. The RX6 is not a rocket but in the 4-6 wt categories they are in my opinion a moderate fast action. I build a fair amount of them for people who want a nice casting back up rod that won't break the bank.
